Is It Any Good?

Although some of its touch features may cause a bit of frustration, this math tool is an excellent and comprehensive way for kids to learn and practice subtraction. Kids have the opportunity to visualize and develop an understanding of subtraction through the use of models, which is a much deeper approach than simply using memorization. Kids will enjoy earning blocks and revealing the mysterious illustration, with the speed round being particularly engaging as kids race to beat the clock. The interactive number line is useful for visualization, but it's sometimes difficult to tap the correct answer, so kids may get it wrong even if they know the correct answer. Also, the narrative about Professor Possum isn't apparent in the actual app; there doesn't seem to be a unifying narrative at all. In terms of the practice itself, however, having multiple approaches to each problem help kids access math concepts in several ways.

Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
